The sum of the two vectors and is
Geometrically, the sum of two vectors is the diagonal of the parallelogram
whose sides are generated by the two
The difference of the two vectors and is
This can be represented geometrically as the sum of the two vectors and .
The scalar multiple of a vector by the scalar c is performed by multiplying each coordinate by the scalar:
This has the effect of multiplying the length of the vector by | c |, maintaining the same direction if c is positive, and reversing direction if c is negative.
